Your example works for me in IE8, it creates a check box that is checked. If you have an example that fails, reopen the ticket with a complete test file.

FYI, although it doesn't seem to affect your example, perhaps it is relevant. If you don't specify a type when creating a checkbox in IE, it defaults to text. Once created, it can only be changed once. This is a limitation in IE.

I have exactly the same problem - I've attached an example which doesn't work in IE6 or IE7. It appears to work in IE8 however, which is somewhat confusing since I originally ran across the problem there.

Unfortunately, this is due to an underlying bug in IE. When a checkbox element is appended (independently of jQuery) it always loses the checked attribute. There isn't a simple workaround at the jQuery level.
